+Support for ThinLTO
+-------------------
+
+LLVM now supports ThinLTO compilation, which can be invoked by compiling
+and linking with -flto=thin. The gold linker plugin, as well as linkers
+that use the new ThinLTO API in libLTO (like ld64), will transparently
+execute the ThinLTO backends in parallel threads.
+For more information on ThinLTO and the LLVM implementation, see the
+`ThinLTO blog post <http://blog.llvm.org/2016/06/thinlto-scalable-and-incremental-lto.html>`_.
